If a typical acrylic roof coating having weight solids of 67%, at 12.0 pounds per gallon, were applied at 3 gallons per square, it would add 24 pounds per square to the weight of the roof. So the weight would increase by 0.24 lbs per square foot. If a scrim were imbedded into the coating, that would also be factored in.
